This pharmaceutical-grade calcium carbonate features high purity, with a calcium carbonate content of over 99.5%. It strictly controls heavy metal and microbial indicators to meet strict pharmaceutical standards. Its uniform particle size distribution supports a dissolution rate of over 95% at 37°C within 30 minutes, which is notably higher than that of regular calcium carbonate products and supports favorable bioavailability. It complies with USP 27 and EP 9.0 pharmacopoeia standards, making it suitable for the production of high-end pharmaceuticals and health products. It helps manufacturers address challenges related to product safety compliance and calcium absorption efficiency.
The product has a calcium carbonate content of not less than 99.5%, with a median particle size D50 of 5-8μm, and the content of heavy metals such as Pb, As and Cd is no more than 0.5mg/kg respectively. The total microbial count is ≤100cfu/g, the pH value ranges from 9.0 to 10.5, and the moisture content is ≤0.15%. The ignition loss is ≤1.0%, the dissolution rate is ≥95% at 37℃ for 30 minutes, and it fully complies with USP 27 and EP 9.0 pharmacopoeia standards, ensuring its safety and effectiveness in medical applications.
This pharmaceutical grade calcium carbonate is mainly used in the production of calcium supplement medicines and health products, such as calcium tablets, calcium oral liquids and chewable calcium supplements, providing high-quality calcium supplementation for the elderly, pregnant women and adolescents. It can also be used as a pharmaceutical excipient for tablet filling and binding agent, improving the forming performance of tablets. In addition, it can be used as an antacid to neutralize excess gastric acid, relieving symptoms of stomach discomfort, and is widely recognized by domestic and foreign pharmaceutical enterprises.
